Konstantin Shvachko resolved MAPREDUCE-1042.

    Resolution: Won't Fix
> rumen should be able to output compressed trace files
> -----------------------------------------------------
>                 Key: MAPREDUCE-1042
>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1042
>             Project: Hadoop Map/Reduce
>          Issue Type: Improvement
>          Components: tools/rumen
>            Reporter: Dick King
>            Assignee: Dick King
>             Fix For: 0.22.0
> rumen is used primarily to create job trace files which are then processed by other tools.
> These trace files can exceed 100 gigabytes.  However, gzip compression normally achieves
15:1 compression on these traces.
> I would like to modify rumen so it can output compressed files directly, rather than
outputting unwieldy uncompressed files and letting me compress it later.
